E N D Presentation Transcript Learning Target: Seed Dispersal I Can Describe different ways that seeds can be dispersed and explain advantages of the different methods I Will Define seed dispersal List methods of seed dispersal including examples of plants for each method Discuss advantages of each method Seed Dispersal Dispersal (the process or result of the spreading of organisms from one place to another) is important because: It spreads the progeny (offspring) in order to colonize new environments Reduces competition for resources with parents Reduces chances of predators destroying all of the plants yearly seed production Self Dispersal Plants disperse their seeds by forceful ejection Explosive fruits Witch Hazel Squirting Cucumber Self Dispersal The peanut plant sows (buries) it own seeds Wind Dispersal Fruit and seeds may have special devices for wind dispersal Plumes catch wind currents Dandelion Trees take advantage of their great heights for wind dispersal Fruits with wings are used to slow descent to land Maple Ash Fruits and/or seeds use flotation devices to travel by water ( in rivers, oceans, etc) Fruit may have air spaces and corky floats Palm Coconuts Water Dispersal Animal Dispersal Many plants depend on animals for seed dispersal Offers nutritional reward Animals learn to recognize ripened fruit colors Fleshy fruit eaten and seeds dispersed in feces Animal Dispersal Some dry fruit attach and cling to animals fur (e.g

In some cases they appear to be hybrids of graphene, in other cases strictly biological, perhaps from sources that have hybridized them
